I found it very pleasant that Aira did not turn out to be some- dimwitted, scared girl, and also liked that she had similar “special” qualities in spite of not being the actual saintess. Sei’s perspective is also interesting, since we got to catch a glimpse of what a “villainess misunderstood” story would look like from a third POV.
I like that they also didn’t just do an isekai then either 1) never reference it again or 2) over-reference it to the point where they’re overpowered unreasonably (since this isn’t that genre, though I like those too). Aira’s personality and behavior was because of her real world experiences, and Sei being familiar with the concept of isekai and magic because of her gaming hobby are both nice details that don’t feel too in-your-face.
The romance between Al and Sei is also really comfy every time I get to see it. Their relationship started because Sei saved his life, and as they spent more time together he gradually began to develop feelings for her (and same with her). I think that’s very fitting for the genre and it’s more like what Sei would have been used to as an adult from our world, which I appreciate. Also on that note, I like that there’s no crazy jealousy or irrational behavior so far in the relationship too
Their friends support them and are happy to see where things are going~
This is getting sooo long BUT I must also add that I actually also liked the way Kyle was written too. He’s a young crown prince who was too immature to mind his mistakes, but doesn’t seem absurdly stupid or evil. We know he’s still a teenager — a likely spoilt one at that (even if not by the king) — and that he was really excited to be a part of the whole saintess operation. In a sad way, it makes sense he only saw the cute young girl close to his age instead of the tired business woman. Furthermore, he wasn’t in love with Aira or anything, unlike how these stories usually go. The reason he was acting so out-of-line was more out of guilt that he felt towards her, which is ANOTHER detail I liked. It makes his accusations and overprotectiveness more explainable, and makes him seem less like a judgemental abusive brat.
